Food poisoning classification

The concept of food poisoning implies acute
polyetiological non-communicable disease resulting from
eating food in which there was a reproduction of certain
microbes and (or) accumulation of toxins, both microbial and
non-microbial nature, as well as toxic chemical or
natural origin.

By type of pathogen that caused the disease, food poisoning
classified into:

  • microbial – microbial poisoning is divided into two main
    groups – food toxicoinfections and food toxicosis or
  • non-microbial (poisonous mushrooms, chemicals, poisonous
  • and unknown etiology.

 Causes of food poisoning

  • Eating foods produced in violation of
    production technology;
  • Eating improperly stored foods;

poor quality product make it safe and usable in
food. However, this is a very dangerous tactic – poisonous mushrooms remain

die when boiling and botulinum toxin can be inactivated
only after half an hour boiling!
